I don't understand the question.

JetBlue is dropping AMEX and converting to a Barclay's branded card. The final details have yet to be released regarding the new co-branded cards.

I have decide to roll my account into the AMEX Blue product. It fits my spending habits the best.

I'll most likely open a new account via Barclay's to accumulate points but I see my purchase frequency dropping. There are far less internal perks from their system than AMEX (Early event tickets, great customer service).
